SPECIFICATION forming part of Letters Eatent No. 665,725, dated January 8, 1901?.'

To all when?, it may concern.

Be it known that l, RUDOLPH G. BEKER, of .Youngstownz in the county of Mahoning and State of Ohio, have invented new and usefnl Improvement in Upsetting-Presses, of v which the following is a full, clear, and exact descriptiom reference beineP had to the accompanying` drawings, forming part of this specification, in which- Figure l shows in plan view, partly in horizontal section, a machine embodying my invention. Fig. 2 is a longitudinal section on the line Il'. II ol Fig. l. Fig. isy a vertical cross-section on the line III lll of Fig. l.

My invention-relates to a machine in which hot metal rods are fed automatically, are ont into exact lengths when in the viscous state, and are then upset fer the purpose of forming bolts, rivets, andthe like.

In the' drawings, 2 represents heatingfurnace, and 3 4 are circular feeding-disks in front of the door of the furnace. The lower disks el- 4 are driven by gearing 5 G, and the upper disks are preferably not positively driven, nut are held down upon the hotrod 7, which is being fe'd by suitable means, preferably by being journaled on levers 8, provided with a weight 9, a fQot-leverldbeing provided to enable the levers S to be raised to 3o Ilift the disks from the rod when desired.

ll is anic-opening through which the rod 7isfed. l

A l2 is a cu* ting and gripping die, adapted to .move across the die-opening.

13 is a companion gripping-die.

14 is a heading-die carried by plunger l5,

which is reciprocate'd by a pitman 16 or other suitable device.

l' is a stop set in advance of the die-open- 46 ing ll and adapted to stopthe feed ofthe rod 7 when it has .been advanced the proper length. This stop i's movable into and ont of the path of the rod bysuitable mechanism, preferably by a Wedge 18 on the under side of the-bar lf), to Which the' bar is connected, and a roller 2O on the plunger l5, over which the bar ltis set, thus imparting a rising and falling motion to the stop. v

The operationisas follows: Ther-od 7 having been heated. in the furnace 2 is introduced between the disks 3 4, and the positive rI-.pplica'tion led January, 1900. Serial No. 564. (No modell) rotation of the lower disks cansesit to ad-' rance through the die-opening il until ,it en` gages the stop 17, the disks meanwhile being` revolved by friction.v vVhen thc-end of the rod en;V ses the stop, the disks 4 will ro-" tate idly aan nst the rod 7 and the disks 3 will stop, wherenpon'the die l2 is caused to advance and a section ol 'the rod is sheared oil' and carried against the die 13, where it is gripped. The plunger li meanwhile advances, causingr the die 1l to engage the end of the cut section of the rod and upset the same.. Simultaneously with the advance 'of the plungeri the stop 17 is raised by the acrod is cut, as above explained, the disks begin to act to feed another section through the die ll, the plunger recedes, the stop' descends, and the actions above described are repeated.

Nithin the scopev of .my invention as delined in the c-lairnsthe number ol rollers may bc varied, nngrooved disks may be substituted for the grooved disks shown in the drawings, and changes in the driving mechanism may be made, since rVhat l claim is l. l. The combina-tion Aof oppositely-located heated metal bar or red betweenthem, mech! lanism for continuously driving on'e only ci said disks, the other being driven merely by' Contactwith the red, mechanism for checkin-g the rodor har at a'delinite peint while con- Atinuonsly d riven by the "Slis, and means fer cutting the rod; sub .ally as described.

2. The combination oan upper an d a lower feeding-dish hax-*inggrooves to receive a heated rod or bar, mechanism lor d ri vin g the lower disk only, the upper disk being an idler arranged to press yieldingly on the rod or bar and be driven thereby, mechanism for checking the, h ot rod at a definite point While acted upon by the disks, and mechanism for cutting the rod when sostoppcd; substantially as deseribed.

3. In a machine for upsetting hot metal, the combination of oppositely-located circular feeding-disks having'grooves te receive ahnt tinnonsly driving-one of said disks only/the other being an idler driven by contact with metal rod between them, mechanism for contion ofthe parts 1S, 19,'and 20. As soon the circular eedmg-disks 'arranged to receive a 'the ,rodi 'nieans'fxorfehecking the hoi', red' at a l' definite point,'andline.ehan'ism for'entbingand upsetting the rodg'jsubspantially as described; f 4. Th ecembination with a heating-f urnace,

5. The'combina'ion of oppositely-located groeved disks arranged EQ receive a' heated metal red between them, mechanism ferdriv ing one of said disks positively and continu-v 0nsly,' the ether dislit'being.,r an idler arranged to press yieldingly on 'the bar and be driven thereby, a step arranged be cheekftlie rod an, a definite point, While it, is eenifinuously acted uponl by thedisks, mechanism for moving the rod into and out o'f positiomand mechanism foi-cutting the bar after it; is siepped; substantially 'as described.
